To all whom zit/may concern.-

Be itknown that I, ALBERT E. AYEn, a citlzen of the United States, residing in Chelsea, in the county of Suffolk and- State of lliassachusetts, have invented an Improveme nt'in Edge-Finishing Machines,fof which the following description, in connection with edge the accompanying drawings, is a specificar tion, like characters on the drawings repre senting like parts.

- This invention relates to a machine for trimming theedges of the soles and heels of boots and shoes, and is herein shown as embodied in. a machine for trimming the edges of the soles of boots and shoes.

The invention has for its object to rovide' a simple and eflicient machine for t is urpose and one with which a cut of uni cm depth may be obtained. For this p ose I employ acutting tool or head which is set to arotatable shaft and is provided with a plurality of knives or cutters with which 006 crirtes' a bed against which the work may ear and which is" connected with the shaft to rotate therewith, et which is capable of radial adjustment wit relation to said shaft to ad-] just the said bed with relation to the cutting and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 15 an elevation of an edge-trimming machine embodying this invention; Fig. 2, a section on the inc 2 2, Fig. 1, taken on an enlarged scale; Fig. 3, a section on the line 3 3, Fig. 1 Fig. 4, a sectidn on the line 4 4, Fig. 1, taken on an enlarged scale; Fig. 5, a section on the line 5 5, Fig. 1, taken on enlarged scale; Fig. 6, a section on the line 6 6,

F' .5; and Fig. 7, a longitudinal sectional detai through the mainshaft shown in Fig. 1.

Referring to Fig. 1, (t represents the head of a rotary edge-trimming machine in which is supported in suitable bearings a shaft I), provided with a driving-pulley c and with a I The bed may be longitudinally adjust able on its shaft, as will be described. These fiywheel d. The shaft 1) has fast on it a rotary cutter comgrising a cutter-head e, having fast to it, as ripheral knives or cutters suitably shaped to cut or trim the edge of t 1e sole of a boot or shoe. The kniv s or cutters 9 have cooperating with them a bed consistin in the present instance of an annularrim it, connected by an inclined rim 'l to a larger annular rim 7', said rims being provided with suitable slots is, into which the knives or cutters project, as represented in Figs. 1 and 2.

. The rimy' is attached to a sleevem of lar er diameter than the shaft (1. and extended through a bearing-hub n and has on the opposite side of the bearing-hub n a collar 0,

from its circumfe ence toward the sleeve. (See Fig. 5.) T e annular bed may be detachably secured to the sleeve m and for this purpose may be screwedthercon. (See Fig. 7.) The slot 29 is designed to receive a stud or pin projecting from a ring r; movably secured to a second ring 10, which latter is provided on its inner circumference with a gitudinal slot 13 in the shaft F) (see Fi 7) and constituting a key by means of which the ring 10 and the bed connected therewith are secured to the shaft 12 torotate therewith. Provision is made for the bed to have a limited rotary movement in its bearing, and for this purpose the ring 1' is provided with an annular groove 14, into which project fingers 15 on bars 16, attached to the pcriphery of the ring 10, as by the screw 17. (See Fig. 6.) The ri; I an annular recess to receive a spring 18, one end of which is fastened to the ring 10 and the other end of which is fastened to the ring 1", the ring 1' being mounted to turn on the ring 10, as clearly shown in Figs. 6- and 7. The movementof the ring r on the ring 10 in one direction is limited by a stop, shown as a one of the arms 16. The stop 20 is located with relation to the arm 16 so that the rota- ,tion of the shaft 1) in one direction carries with -it the ring 'r and the bed connected therewith by means cf the pin q and slot p. The shaft b between the head a and the ring 1 1Q may be encircled by the helical spring 22 to y'screws f, a pluralitypf peprovided with a slot 13, extended radially stud or projection 12, adapted to enter a lon- 10 is provided with pin or projection 20, which cooperates with v zoo The bcarhtg-hub n is capable of radial moi'emcnt with relation to the shaft a, which may be effected by means of a thumb-screw work in the proper or desired manner. 3 movable bed against which the edge of the L25,c. :tend(- d into a suitable socket in an arm 2% projecting radially from the hub n, and said bcaringdiubmay be secured in its adjustcd position by means of a set-screw 27, extended through an opening 28 in the arm 26 and into a supporting arm or bracket 30,

whirl res the screw and which is extended; ii'mgitudinally of the shaft 1). The

supporting-arm 30 may also be adjustably secured to the head a by a set-screw 31, ex: tended through an opening 32 of larger diameter than the screw 31, and may bemoved loneitildinally by the screw 35.

from the above description it will be seen that the bed supported by the bearing-hub n rotates with the shaft and with the cutterhead 0, and the said bed is capable of being radially adj ustcd with relation to the shaft and the cutter-head, so as to uncover more or less of the cutting edges of the knives, with the result that the bed against which the edge of the sole of the shoe is hold is effectively trimmed by reason of the fact that the shavlogs or trimmings taken off from the edge of the sole are of uniform thickness. The adjusti'ncnt of the bed with relation to the cutter-head and its knives may be effected by the bperator in the present instance while the macl'iil' e is in operation The bed may be detachable from the sleeve m, so that beds of different widths or sizes may be secured to the sleeve m to suit work of different thicknesses, and the longitudinal adjustment of the bearing-hub it permits beds of different widths to be used.

By making the bed which rotates with the shaft radially adjustable with relation thereto I 1111 enabled to obtain'a quick and easy adjustment of the cutting edges of the knife with relation to the work without adjustnent of the knives, thereby effecting a material saving in time in adjusting a machine Ito T e solebears regulates the distance the cutting edge ofthesknife projects beyond the said bed, so as to obtain a uniform shaving at all times and of any desired thickness within making the bed movable longti- I 11* its shaft and providing the sprint; 22 for yieldingly holding the inclined rim or surface i in proper position with relation to the knives the function of a featheredger is imparted to the machine. The spring is is employed to prevent the pin g from binding in the slot 29 during each rota tion of the shaft when the bed has been moved occentrically to the/shaft to uncover more or less of the knives.

I claim 1. In a machine of the class described,'in combil'ration, a rotatable shaft, a cutter-head fast thereon, a plurality of cutters extended from the periphery of said head, a bed provided with slots into which said cuttcr's extend, means to connect said bed with said shaft to caus said bed to revolve with said shaft, means to sup ort said bed out of contact with said shaft, and means to effect movement of said support radially with relation to said shaft while the latter is in rotation, substantially described.
